To all whom a may concern '-Be it known that I, ALLEN. H. KnRNeoon, a citizen of the United States, residing "at Baltimore, in the State of Maryland, have invented'a certain new and useful Improvement in Sliding-Tongue Buckles, of which the following is a full, clear, and exact de scription. '7

This invention relates to that type of buckles known as sliding-tongue buckles, as distinguished from pivoted-tongue buckles, and used on straps forgarments and other articles, and the object of the. invention is to provide an improved construction of sliding-tongue which may be economically made and assembled, and whichis held in place and guided in operation by connection with the frame of the buckle andservestoengage the adjustable end of the strap between it self and an adjacent portion of the frame the tongue or slide member and the frame being so constructed and of such relative proportions and so assembled that both the slide and-the frame are practically devoid of obtrusive elements or members,'and hence the tongue itself may be appropriately designat ed a level slide and the buckle as a whole may equally appropriately be termed a level slide buckle. h

The invention consists of a sliding-tongue buckle having a frame of suitable construction and adapted to be permanently connected with one end or portion of a strap, and having a cross bar which is engaged by a fold of the tongue in such way as to limit the movement of the tongue, and this cross bar and adjacent portions of the frame serve to guide the tongue, the tongue having its biting edge suitably formed to frictionally' or otherwise engage the free or adjustable end of the strap, in the forward movement of the tongue, as I will proceed now more fully to explain and finally claim.

In the accompanying drawings illustrat ing the invention, in the several figures of which like parts are similarly designated, Figure 1 is a top plan view; Fig. 2 is a bottom plan view, and Fig. 3 is a longitudinal section of one form of the buckle of this invention. Fig. 4 is a perspective view of the frame alone. Fig. 5 is a perspective view of the tongue alone. 7

The frame 1 may be of any suitable form or configuration adapted to the uses for which the buckle is designed, and preferably is rectangular in general outline, and has the side bars 2, the front and rear bars 3 and 4,

respectively, the depressed rear cross bar 5 to which is fixed one'end of the strap and the depressed forward cross bar '6, the depression of which may be and preferably is slightly less than the depression in the rear cross barf).

The sliding-tongue 7,

rear edge 9 of'which is made as an upstanding lip, which may be plainor toothed or otherwise formed to get a secure grip upon the strap and for stop purposes. This for-.

as shown in detail in Fig. 5, is of sheet metal, having the transversely slotted leading or forward end 8, the

as to ease and guide the sliding movement 'ofthe tongue. This tongue is formed with a rearextension which is folded'forwa'rdly upon itself as indicated at 12, about the for ward cross bar 64 Preferably this folded portion of the tongue is of substantially the I width of the inside of the frame, so that the tonguein its'longitudinal movements will be guided andsteadied by the frameand 'sup porting cross bar. The loop formed bythe folded portion of the tongue serves also in part to limit the movement of the tongue and in any case insures the retaining of the tongue in engagement with the frame no matter what strain is placed upon it. The upturned edge 9 of the tongue is sufficiently elevated to play in the plane of the frame, and by coming into contact with the cross bar 3 of the frame to prevent the escape of the tongue from the frame in that direction...

It will also be noticed that the forward end 8 of the tongue is in a lower plane than the top portion of the folded or loop-like rear end 12 of the tongue. The drop 13 between these two parts serves as a stop to prevent undue rearward motion of the tongue on the cross bar 6 and also serves to practically close the forward end of the loop against escape of the tongue from said cross bar 6. Not only is forward movement of the tongue limited by the upstanding edge 9,-but it is also limited by the engagement of the part 14 of the loop 12 with the rear edge of the cross bar 6.

The slotted leading end of the tongue and the space between the cross bar 6 and the front bar 3 of the'frame permits the passage of the adjustable end of the strapto be engaged by the tongue, and this free end of the strap is then tucked under the rear cross bar 4 if necessary or desirable.

The construction shown and described provides a very flat or thin buckle, and adadjacent cross bar, and a sliding mits of economical manufacture.

Variations in the details of construction 5 and arrangement of parts are permissible bar of the frame to engage the strap end.

2. A. slidingtongue buckle, having a frame provided with a front end bar and an adjacent cross bar, and a sliding tongue provided with a transversely slotted strap-engaging end'and a rearward extension folded forwardly and forming a loop which encloses the cross bar, whereby the tongue is secured to the frame, said loop being of substantially the same width as the interior distance between the side bars of the frame and freely movable forwardly and backwardly on the cross bar.

. 3. A sliding-tongue buckle, having a frame provided with a front end bar and an adjacent cross bar, and a sliding tongue pro vided with a transversely slotted strap-en gaging end and a rearward extension folded forwardly and forming a loop which encloses the cross bar, whereby the tongue is secured to the frame, said folded extension running lengthwise of the tongue toward the slotted end and having a drop at its forward portion so thatthe cross bar is engaged at front and rear to limit the movements of the tongue. 7 j

4. A sliding-tongue buckle, having a frame provided with a front end bar and an adjacent cross bar, and a sliding tongue provided with a loop enclosing the cross bar and thereby secured to the frame, said tongue having a transversely slotted leading end eX tending laterally on both sides of the frame and underlying the said frame, the loop and the slotted leading end being connected by a dropped portion of the metal of the tongue which serves also to close the loop at its forward end about the cross bar.

A sliding-tongue buckle, having a frame provided with a front end bar and an adjacent cross bar, and a sliding tongue provided with a loop enclosing the cross bar and thereby secured to the frame, said tongue having a slotted leading end underlying the frame and adapted to engage and hold the adjustable end of a strap, said front end having a transversely arranged upstanding lip the edge of which extends up into the frame and between its sides.

In testimony whereof I have hereunto set my hand this 19th day of April A. D. 1922.
